Application August as, 1946, Serial No. 692,588 1 Claim. '(01. 22-61) This invention relates to the production of metal ingots. Considerable material is now lost through the production of faulty ingots. The molten mass frequently develops pipes or air pockets in the ingots. This results in a defective product which is totally incapable of use for many purposes. pose of this invention to obviate this condition.

The present invention makes entirely unnecessary the present need of capping the ingots and prevents same from adhering to the mold during manufacture. Further, the formation of sink heads will be eliminated and liquid steel blow-outs will be avoided.

More specifically the invention provides a means of imparting a constant regular vibration to the ingot mold during and after the pouring operation resulting in the creation of a plurality It is the principal purof more or less parallel continuous undulations I which, for the purpose of illustrating the invention, is shown in the accompanying drawing which forms a part of this specification, and

wherein- Fig. 1 is a view in end elevation, with parts,

in section, of an ingot mold mounted upon a carriageunder vibratory impact, and,

Fig. 2 is a top plan view of 'Fig. 1 taken on the line 2! thereof.

The reference numeral I denotes an ingot mold of conventional type mounted upon a carriage 2 upon track I extending along the pouring platform 4 arranged upon support 5 extending throughout a portion of the shop or mill.

coextensive with one edge of platform 4 is the guard wall 0 formed or provided throughout its length with an inclined shield I disposed forhaving arranged thereupon the reciprocating hammer l3 with its head extending through said window for engagement with a wall of mold i to deliver blows thereagainst at the rate of approximately sixty per minute, said hammer being electrically, compressed air, or otherwise op erated.

In operation the carriage 2 with ingot mold I thereon is moved along track 3 to the point of loading. At the time, and for a. period thereafter, that the molten material is poured into the mold the hammer i3, having been positioned directly opposite to said mold upon runway 9, is operated directing blows against said mold setting up mold vibration that is imparted to the molten material sufllciently agitating same to effectually prevent piping or the formation therein of pockets of air. By slight movement of the carriage i2 upon rails ii in either direction the points of application of the hammer impacts may be varied if desired. This is readily accomplished by the attendant or mechanic in charge. The operator is protected at all times from molten metal, flying sparks and the like by the guard wall 8 and shield or awning I.

What is claimed is: i

In combination with an ingot mold, a movable carriage therefor, a track for said. carriage, a guard wall extendin along said track, a window in said guard wall extending longitudinally thereof. a shield carried by said guard wall coextensive .with said window "and extending outwardly and downwardly from the upper end thereof contiguous to the path of said ingot mold and carriage, a runway adjacent said guard wall 'upon the side thereof remote from said carriage,

rails upon 'said runway, a second carriage movable upon said rails, and a reciprocating hammer carried by said second carriage and extending through said window beneath said shield for engagement with the ingot mold.

wardly toward track I immediately beyond a long wall-window or opening I forming an awning therefor, said window and awning belnt preferably at an elevation approximately onehalf the height of the mold.

' Supported upon a runway 1 carried by braces I. and support l are the rails ll upon which the carriage it runs, said runway being spaced inwardly from, adjacent and parallel to. the said well I and coextensive therewith, said carriage WALTER A. KOSINSKI.
